Correction of wavelength-dependent laser fluence in swept-beam spectroscopic photoacoustic imaging with a hand-held probe

Photoacoustics, 2020
Recently, we demonstrated an integrated photoacoustic (PA) and ultrasound (PAUS) system using a kHz-rate wavelength-tunable laser and a swept-beam delivery approach.

Influence of the Heights of Low-Level Jets on Power and Aerodynamic Loads of a Horizontal Axis Wind Turbine Rotor

Atmosphere, 2019
The influence of the heights of low-level jets (LLJs) on the rotor power and aerodynamic loads of a horizontal axis wind turbine were investigated using the fatigue, aerodynamics, structures, and turbulence code. The LLJ and shear inflow wind fields were

Comparison of Blade Dimension Design of a Vertical Wind Turbine Applied in Low Wind Speed

E3S Web of Conferences, 2018
The type of vertical turbine used for this research was a savonious where the profile of the blade was made in the form of a half-cylinder. The performance of the turbine rotation was strongly influenced by the swept area.
